Yes the check engine light has come on and gone back off.
If I accelerate fast the van has plenty of power.

Were the plugs changed? Have you checked fuel pump pressure as well as the regulator?

Now I have replaced coil, plugs and wires. Fuel pressure is about 55psi at fuel rail. Still no change in rough running.
When I changed plugs there was a raw gas smell in cylinders.

Have you checked the computer to see what trouble codes may still be stored? If I remember correctly, you should be able to do it without a scanner.

Cycle the key from off to the run position (not start) 3 times. The 3rd time, let the key on / engine off. It should read the codes in the odometer area.
